Description
Technical field
The invention belongs to technical field of lithium ion, specifically, the present invention relates to a kind of inbuilt frame polymer lithium ion battery.
Background technology
Energy density is high owing to having for polymer Li-ion battery, environmental protection and the advantage such as to have extended cycle life, and is widely used in electronic product (as MP3, mobile phone, notebook computer), electric automobile, military and space etc.
At present, the packaged type of polymer Li-ion battery is generally directly battery core is placed in aluminium plastic packaging bag to encapsulate, and because the structure comparison of battery core itself is soft, therefore its mechanical safety is lower, to be collided etc. fortuitous event time, easily there is safety problem.And the corner of battery core is not too regular, when being assembled into battery pack, appearance is not satisfactory, but also adds the difficulty of assembling.
In view of this, necessaryly provide a kind of inbuilt frame polymer lithium ion battery, because frame has higher mechanical strength, therefore this inbuilt frame polymer lithium ion battery has higher fail safe, and the assembling of battery pack can be made to become simple and convenient, improve packaging efficiency, improve the appearance of battery.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, and a kind of inbuilt frame polymer lithium ion battery is provided, because frame has higher mechanical strength, therefore this inbuilt frame polymer lithium ion battery has higher fail safe, and the assembling of battery pack can be made to become simple and convenient, improve packaging efficiency, improve the appearance of battery.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of inbuilt frame polymer lithium ion battery, comprise battery core and the aluminium plastic packaging bag for encapsulating described battery core, the surrounding frame of described battery core is provided with frame, and described battery core and described frame are all packaged in described aluminium plastic packaging bag.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and described frame is formed in one.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and the thickness of described frame is 0.1-5mm.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and the thickness of described frame is 0.5-3mm.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and the thickness of described frame is 1.5mm.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and is provided with adhesive linkage between described frame and described battery core.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and the thickness of described adhesive linkage is 0.1-2mm.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and the thickness of described adhesive linkage is 0.5mm.
One as inbuilt frame polymer lithium ion battery of the present invention is improved, and described frame is polyvinyl chloride framework or stainless steel framework.
Relative to prior art, the present invention is by there being the frame of higher mechanical strength in the surrounding frame setting tool of battery core, this inbuilt frame polymer lithium ion battery is made to have higher fail safe, and the assembling of battery pack can be made to become simple and convenient, improve packaging efficiency, the corner rule of battery core can be made simultaneously neat, thus improve the appearance of battery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention and Advantageous Effects thereof are described in detail, but embodiments of the present invention are not limited to this.
As shown in Figure 1, a kind of inbuilt frame polymer lithium ion battery provided by the invention, comprise battery core 1 and the aluminium plastic packaging bag 2 for packaging electric core 1, the surrounding frame of battery core 1 is provided with frame 3, battery core 1 and frame 3 are all packaged in aluminium plastic packaging bag 2, and the front end of battery core 1 is provided with lug 11.
Wherein, frame 3 is formed in one.During actual fabrication, the frame 3 that can be made into one shaping according to the size of battery core, then by battery core 1 directly frame to be located in this frame 3 both can, convenient and swift.
The thickness of frame 3 is 0.1-5mm.The thickness of frame 3 can not be too large, otherwise can affect the energy density of battery; The thickness of frame 3 can not be too little, otherwise the mechanical strength of frame 3 is inadequate, can not play the effect of protection battery core 1 well.
The thickness of frame 3 is 0.5-3mm, and this is the thickness range of preferred frame 3.
The thickness of frame 3 is 1.5mm, and this is the thickness of preferably frame 3, selects this thickness can take into account the energy density of battery and the mechanical strength of frame 3 simultaneously.
Adhesive linkage is provided with between frame 3 and battery core 1.Adhesive linkage can ensure frame 3 securely frame be located in frame 3, come off in frame 3 to avoid battery core 1.
The thickness of adhesive linkage is 0.1-2mm.Adhesive linkage can not be too thick, otherwise can affect the energy density of battery; Adhesive linkage can not be too thin, otherwise can not play good bonding effect.
The thickness of adhesive linkage is 0.5mm, and this preferably selects.
Frame 3 is polyvinyl chloride framework or stainless steel framework.These two kinds of frameworks all have higher mechanical strength, are preferably polyvinyl chloride framework, because polyvinyl chloride framework ratio is easier to one-body molded.
During actual assembled, comprise the steps:
The first step, inserts battery core 1 in frame 3, make battery core 1 just in time frame be located in frame 3, in order to make battery core 1 better be fixed in frame 3, one deck viscose glue can be coated with between battery core 1 and frame 3, formed adhesive-layer;
Second step, the battery core 1 frame being provided with frame 3 is inserted in aluminium plastic packaging bag 2, then injects electrolyte to aluminium plastic packaging bag 2, then is encapsulated by aluminium plastic packaging bag 2.
In a word, the present invention is by there being the frame 3 of higher mechanical strength in the surrounding frame setting tool of battery core 1, this inbuilt frame polymer lithium ion battery is made to have higher fail safe, and the assembling of battery pack can be made to become simple and convenient, improve packaging efficiency, the corner rule of battery core can be made simultaneously neat, thus improve the appearance of battery.
It should be noted that, according to the above description the announcement of book and elaboration, those skilled in the art in the invention can also change above-mentioned execution mode and revise.Therefore, the present invention is not limited to embodiment disclosed and described above, also should in the protection range of claim of the present invention to equivalent modifications more of the present invention and change.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the present invention.
